CVE-2024-8602 Information

Description

When the XML is read from the codes in the PDF and parsed using a DocumentBuilder the default settings of the DocumentBuilder allow for an XXE (XML External Entity) attack. Further information on this can be found on the website of the Open Worldwide Application Security Project (OWASP). An attacker could theoretically leverage this by delivering a manipulated PDF file to the target and depending on the environment various actions can be executed. These actions include:

Reading files from the operating system
Crashing the thread handling the parsing or causing it to enter an infinite loop
Executing HTTP requests
Loading additional DTDs or XML files
Under certain conditions executing OS commands
